The relevance of local removal and release of norepinephrine (NE) for antecubital venous plasma NE concentration was studied in 22 healthy subjects. Arterial and venous plasma NE and forearm blood flow were measured during intra-arterial infusion of two doses of NE, intra-arterial NE infusion with two doses of sodium nitroprusside, intravenous infusion of NE with intra-arterial infusion of four...

The vasodilation induced by systemic insulin infusion is mediated by nitric oxide and is impaired both in obese subjects and patients with essential hypertension. Whether this vascular defect explains the metabolic resistance to insulin action is uncertain. In 8 overweight male patients with essential hypertension, we used the double forearm (ie, infused versus control) technique, combined with...

the aim of this study was to reveal biometric peculiarities of new zealand white rabbit antebrachium (radius and ulna) by means of three-dimensional (3d) reconstruction of multidetector computed tomography (mdct) images. under general anesthesia, the antebrachiums of a total of sixteen rabbits of both sexes were scanned with a general diagnostic mdct. biometric measurements of the reconstructed...

Background: Salvage procedures for distal radioulnar joint (DRUJ) arthritis, like the Darrach or Sauvé-Kapandji (S-K) procedures, often result in extensor tendon ruptures at ulnar stump. Radioulnar instability is considered underlying cause and stump stabilization techniques are employed. This study investigated instability, irritation, effectiveness of following salvage procedures. Methods: Si...

Animal studies have demonstrated that CNP causes endothelium-independent vasodilation, which is limited by neutral endopeptidase (NEP) activity. However, the vasodilating mechanism of CNP in humans is still unknown. Therefore, we investigated the vasodilator actions of CNP in human forearm resistance vessels before and after inhibition of nitric oxide (NO) and then prostacyclin production and a...

Prono-supination takes place over the full length of the forearm, the whole forearm thus being one single joint. Any change to the configuration of the proximal (PRUJ) or distal (DRUJ) radioulnar joints or to the forearm diaphyses and the connecting interosseous membrane (IOM) can result in loss of forearm rotation by either mechanical interference and/or by pain induction. Capsule retraction a...

BACKGROUND AND OBJECTIVES Hemodialysis needs an arteriovenous fistula (AVF) that may influence the structure and growth of nearby bone and affect bone mass measurement. The study analyzed the effect of AVF in the assessment of forearm bone mineral density (BMD) measured by dual energy x-ray absorptiometry (DXA) and examined its influence on the final diagnosis of osteoporosis. DESIGN, SETTING...

[Purpose] It is unknown whether handgrip strength dominance is related to the size of the forearm flexor muscles. The purpose of the present study was to investigate the relationship between side-by-side differences in handgrip strength and forearm muscle thickness. [Subjects] Thirty-one young women (26 right handed and 5 left handed) between the ages of 20 and 33 years volunteered to participa...

background: mycobacterium marinum infection has a worldwide distribution and the organism occupies many aquatic environments. infections in human consist of nodular cutaneous lesions that can progress to tenosynovitis, arthritis, and osteomyelitis. case presentation: a 27-year-old man was presented with a history of swelling and exudative erythematous lesions and pustules of the right forearm. ...

introduction: advanced lip carcinomas can invade adjacent structures. performing surgery for these cancers will lead to defects in this anatomically and functionally important area and will cause post-op difficulties such as drooling, speech alterations and aesthetic considerations, if not properly managed. case report: in this study, we will introduce a radial forearm free flap with palmaris l...
